The water nowadays contains a lot of contaminants due to pollution in the environment. This can be dangerous to human health. However, with the advancement of technology there is no problem to which there hasn’t come any solution. The water purifiers play a very important role in this scenario. These purifiers have been designed with different purification methods. Firstly, let us know what are the different types of water purification methods?

Different Types of Water Purification Methods
Water purification is the must when it comes to any living organisms. The harmful contaminants in the water may lead to severe water-borne diseases and also to death. However, the purification can be done in different ways. So, let us look at the possible methods of water purification.
These are the different methods of water purification. They are useful in providing us with safe and healthy drinking water. But, wouldn’t it be great if you have a water purifier in your house which performs multiple water purification methods? Yes, definitely it would be. But to decide on which is the best water purifier for home in India, one needs to know the types of water purifier. So, let us get started with knowing them.
Types of Water Purifiers
On the basis of various water purification methods, different water purifiers have been designed for homes in India. Let us go through the list of types of water purifiers available in India.
UF (Ultra-Filtration) Water Purifier
UF or Ultra-Filtration does not use electricity and any chemicals to purify the water. It uses hollow fibers of a membrane made of a thin layer of material capable of separating water and other particles in water. The UF purifiers are quiet similar to RO purifiers, but the RO can block very minute particles and UF on the other hand can block only larger particles.
UF is ideal for water with low TDS level. It does not remove chemicals; it simply blocks germs like bacteria and viruses. It is not suitable for hard water purification. Thus, the hard water still remains hard water even after purification.
UV (Ultra-Violet) Water Purifier
UV or Ultra-Violet water purifier does not use any chemical during purification process. In this purifier, water has to pass through a small UV lamp fitted in the filter. This water is exposed to UV light which kills all water-borne diseases causing microorganisms, pathogens and cysts. The water is then safe for consumption.
However, in the UV water purifiers the dead bodies of the microorganisms stay in water and are not removed. But, the water is still safe for consumption. UV purifiers are suitable for low level TDS water and are incapable of purifying hard water.
These purifiers have high purification rate compared to RO, UF and activated carbon. It does not alter the taste of water. Also, it does not remove chemicals like fluoride, arsenic, chlorine, etc.
RO (Reverse Osmosis) Water Purifier
The RO water purifiers are capable of removing metal particles like arsenic, fluoride, lead, chlorine, nitrates and sulfates. It uses semi-permeable membrane to purify water. The water pump in the RO water filter pressurizes the raw hard water to pass through the RO membrane which removes all the mentioned metal particles.
The RO water purifier also changes the taste and odor of water giving you safe and healthy water for consumption. These purifiers are commonly available in India. They are suitable for water from different sources like tap water, municipal water, borewell, etc. It is a must in the region where TDS level is greater than 200.
They come in different types like wall-mounted or counter-top RO water purifier and Under-sink or Under-Counter RO water purifier. No wonder, RO water purifier gives out plenty of waste water which should be optimally used. There are various uses of waste water from RO purifier.
Activated Carbon Water Purifier
Activated Carbon is most suitable for water borne disease causing pesticides and heavy metals. It is most effective in removing chlorine from water. It is made of carbon which is divided into small pieces. It removes the chemicals from the water which makes is taste and smell bad.
The activated carbon improves RO membrane life by blocking chlorine and other particles which are damaging RO membrane. It is not suitable for hard water, since the hardness of water remains same even after filtration. One needs to actively use such filter to avoid growth of microorganisms like bacteria and viruses on activated carbon surface.
This water purifier is used along with other purification technologies like RO, UV. This filter basically catches unwanted dust or mud particles in the water. The sediments collected in this filter may be rust flakes of metal pipes, mud particles or sand. It also removes turbidity of water.
In India, most of the sediment filters are made of cotton, polyester fibers. Sediment filters are placed before the inlet of any other water purifier. The water outlet of sediment filter is connected to RO or UV water purifier as the inlet.
These are the few types of water purifiers available in India. However, many of the water purifiers have the technology of all the types of purifiers inbuilt in a single product. This helps in multi-stage purification of the water which provides you with safe and healthy water for consumption.
Concluding Thoughts on Types Of Water Purifiers
The different types of water purifiers enables you to select the most suitable water purifier for your home. Also, we have made you aware of many different methods of purification. Not just that there are several factors to consider to buy the best water purifier. One needs to go through them before making the best buy.
